B3941 SATURN Description
The driver and passenger seat heaters are controlled by the Driver Seat Module (DSM). Power is supplied to the driver seat cushion and back heater elements through inpidual voltage supply circuits. Power is supplied to the passenger seat cushion and back heater elements through a common voltage supply circuit. All of the driver and passenger seat heater elements are grounded by the DSM through inpidual low side drive control circuits. The heater element control circuits are pulse width modulated to ground by the DSM in order to control the seat temperatures by regulating the current flow through the heater elements. The Diagnostic Trouble Code (DTC) sets when the DSM determines that one of the seat heater element voltage supply circuits is shorted to ground.
